Cost of capital and earnings transparency
研究发现盈余透明度越高的公司，其资本成本越低，该结论在控制已知影响因素后依然成立。
We provide evidence that firms with more transparent earnings enjoy a lower cost of capital. We base our earnings transparency measure on the extent to which earnings and change in earnings covary contemporaneously with returns. We find a significant negative relation between our transparency measure and subsequent excess and portfolio mean returns, and expected cost of capital, even after controlling for previously documented determinants of cost of capital.
